Introduction
The SC70 DAC Evaluation Module is an evaluation board containing all the necessary components to
evaluate the 6-pin, SC70 series of high-performance, digital-to-analog converters from Texas Instruments.
The EVM is designed so that a single printed-circuit board (PCB) supports the entire family of high-speed,
12- and 16-bit serial DACs.

The EVM is designed so that a single printed-circuit board (PCB) supports the entire family of high-speed,
12- and 16-bit serial DACs.
The modular EVM form factor allows for direct evaluation of the DAC's performance and operating
characteristics. This EVM is compatible with the 5-6K Interface Board (
characteristics. This EVM is compatible with the 5-6K Interface Board (
) from Texas Instruments
as well as the HPA-MCU Interface Board (
). As part of a SC70 DACEVM-PDK kit, this EVM is
supported on the DXP Platform using the modular motherboard MMB0.

Analog Interface
For maximum flexibility, the SC70 DAC evaluation module (EVM) is designed for easy interfacing to
multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a
convenient 10-pin, dual-row, header/socket combination at J2 (
